Abstract: HT300 (Cast Iron) is widely used in heavy machines, and the metal magnetic memory (MMM) technique can is used to evaluate early damage of the following metal while calculating the stress concentration. An experimental investigation of the effect of stress on permeability of HT300 has been undertaken on cast iron. The result showed that the stress can alter the permeability of the material which will amplify the magnetic field of the specimen. Further, simulation was used to evaluate the characteristics of magnetic signal under different conditions. The present work indicate that the MMM can detect stress concentration and early stage of damage effectively.

Abstract: The problem of topology optimization of large spindle box of heavy machine was studied. Based on ICM topology optimization, the parameters topology optimization were changed by sensitivity analysis and the sensitivity parameters were normalized; the topological parameters were modified and removed which judgment based on the sensitivity of the cross-section unit cell in the progress of optimization. Example shown that the integrated optimization method made the structure optimization more intuitive, not only avoided effectively the occurrence of the load strange in the optimization process, but accelerated the convergence speed.

Abstract: In this paper, a kind of product numbering system for single piece/small batch customization manufacturing and its process organization is put forward based on the current status of Shenyang Heavy Machine Manufacture Group Co. Ltd. and the trends of advanced manufacturing technology such as PDM/ERP etc. The numbering system developed includes all of relative public information data such as product order, design, process plan, manufacturing, marketing, consumer servicing and so on. A more favorable condition is created to realize the share of relative information in the different departments of the company and to improve the response to the market.
